I purchased this from Amazon several years ago but have never used it and have kept it stored at home. The following is quoted from Amazon: 【Large Capacity Storage】Despite its compact size, it can hold up to 16 passbooks, medical record books, mother and child health handbooks, pension books, and passports, as well as 8 cards. It features accordion-style pockets that allow you to quickly access items when opened. 【Magnetic Interference Prevention】Each pocket is equipped with a function to prevent magnetic interference caused by contact between passbooks and cards. *The magnetic interference prevention and skimming prevention functions may deteriorate depending on usage conditions. In the unlikely event that IC cards are unintentionally read or other functional issues arise, please contact us. 【Irresistible Texture】The surface uses textured genuine leather (shrunken leather), which is resistant to scratches and stains. The simple design is often used by famous brands, giving it a luxurious feel just by owning it. 【Size】 1.5 depth x 12 width x 18 height cm Please consider it.
